Taliban says 5 civilians killed in bomb attack at Kabul mosque

At least five civilians were killed in a bomb blast at the entrance to a Kabul mosque Sunday, a Taliban official said, describing the deadliest attack in the Afghan capital since U.S. forces left at the end of August.

There was no immediate claim of responsibility, but suspicion fell on Islamic State (ISIS) extremists who have stepped up attacks on the Taliban in recent weeks, particularly in the ISIS stronghold in eastern Afghanistan.

An apparent roadside bomb went off at the gate of the sprawling Eidgah Mosque in Kabul at a time when a memorial service was being held for the mother of Taliban spokesman Zabihullah Mujahid. Qari Saeed Khosti confirmed the deaths.
